摘要： In a magnetic recording device, a semiconductor laser (LD) is disposed at a position with a predetermined distance from a swing arm having a slider. The laser beam output from the LD is irradiated, via a beam converter and a mirror, to a spherical aberration lens that generates spherical aberration. The laser beam transmitted through the spherical aberration lens is directed to a light incident opening of the slider at a constant angle (perpendicularly), and then to a position of a recording medium at which information is recorded, thereby performing thermal assist at the magnetic recording time.

摘要： A magneto-optical head includes an optical head provided with a light-focusing device for focusing a beam spot on an information-recording medium and a magnetic head provided with a magnetic-field applying device for applying a magnetic field to the information-recording medium. The optical head and the magnetic head have the same rotation center and are arranged to rotate together in respective planes parallel to the information-recording medium.The relative position shift between the beam spot and the magnetic-field applying device, which occurs when the beam spot follows eccentric components of the information-recording medium, is avoided. As a result, a magnetic-field applying device can be miniaturized, resulting in decrease in power consumption and in inductance of the magnetic head. Consequently, data can be recorded at a high frequency, thus improving the recording density and transfer speed.

摘要： A magneto-optical flying head utilizes a steerable mirror in combination with a light source and a lens to write and read data onto a magneto-optical storage disk. A beam of laser light transmitted from the light source to the optical head is reflected onto a steerable micro-machined folding mirror. The reflected light from the folding mirror is directed through an embedded micro-objective GRIN lens. Fine tracking and short seeks to adjacent tracks are performed by rotating the mirror about an axis of rotation. In this way a focus spot is scanned back and forth in a direction which is approximately parallel to the radial direction of the storage disk.
